SamplingProfilerIntegration and SamplingProfiler improvements (2/3)
Summary:
frameworks/base
- fix profiling to collect data beyond the first snapshot
- avoid many small files, accumulate data over process lifetime
libcore:
- add support for VM specific sampling, trying to cut down overhead
- added support for converting snapshot files to text format
- fixed race in profiler when stopping
dalvik
- added VMStack.setThreadStackTrace interface for filling a stack
trace into an existing StackTraceElement[]
Details:
frameworks/base
Changed snapshots from text to binary hprof format (bumping version to 3)
Changed from one file per snapshot to one file per process lifetime.
Restart profiling after snapshot.
core/java/com/android/internal/os/SamplingProfilerIntegration.java
Add quick test in maybeSnapshot to avoid doing work when the
SamplingProfilerIntegration is disabled. Make maybeSnapshot
private. Remove unneeded memory allocation in handleLowMemory.
core/java/android/app/ActivityThread.java
libcore
Added ThreadSampler interface. This allows VM specific thread
sampling optimizations. The portable version continues to use
Thread.getStackTrace().

dalvik/src/main/java/dalvik/system/profiler/PortableThreadSampler.java
dalvik/src/main/java/dalvik/system/profiler/SamplingProfiler.java
Add VMStack.setThreadStackTrace and use in new DalvikThreadSampler
to avoid allocating a full stack trace when only a limited depth
is desired.
dalvik/src/main/java/dalvik/system/profiler/DalvikThreadSampler.java
dalvik/src/main/java/dalvik/system/VMStack.java
Refactored BinaryHprof.readMagic out of BinaryHprofReader so it
can be used by HprofBinaryToAscii converter to probing file
types. Added magic number constant to be shared between readMagic
and BinaryHprofWriter.

dalvik/src/main/java/dalvik/system/profiler/BinaryHprofWriter.java
dalvik/src/main/java/dalvik/system/profiler/HprofBinaryToAscii.java
Removed unneeded HprofWriter interface. Changed to simpler static
interface to write HprofData to binary and text formats.
dalvik/src/main/java/dalvik/system/profiler/HprofWriter.java
dalvik/src/main/java/dalvik/system/profiler/AsciiHprofWriter.java
dalvik/src/main/java/dalvik/system/profiler/BinaryHprofWriter.java
dalvik/src/test/java/dalvik/system/profiler/SamplingProfilerTest.java
Added support for reading snapshot files created by
SamplingProfilerIntegration by stripping the text header to allow
easier conversion to the text format.
dalvik/src/main/java/dalvik/system/profiler/HprofBinaryToAscii.java
Fixed race between Sampler and
SamplingProfiler.stop. SamplingProfiler.stop previously simply
called the Sampler's TimerTask.cancel method, but this does not
wait for a currently running Sampler to finish. The TimerTask
documentation says the only reliable way to do this is to have the
run() cancel itself, so that is what is now done, with new code to
ensure that SamplingProfiler.stop does not return until the
Sampler has been terminated.
dalvik/src/main/java/dalvik/system/profiler/SamplingProfiler.java
dalvik
Refactored VMStack_getThreadStackTrace to create helper getTraceBuf
used to implement new VMStack_setThreadStackTrace. The new version
interface fills an existing StackTraceElement[], avoid allocating
unnecessary StackTraceElements.
vm/native/dalvik_system_VMStack.c
Refactor dvmGetStackTraceRaw to create dvmSetStackTraceRaw which
fills in an existing, potentially smaller, StackTraceElement[].
vm/Exception.c
vm/Exception.h
Change stack depths to be unsigned to avoid signed/unsigned comparison warnings.
vm/Ddm.c
vm/Exception.c
vm/Exception.h

Remove the stopAtPrivileged argument.
It's superfluous now.

Remove method level hiding within hidden classes.
This change also removes braces surrounding a properly placed @hide
annotation.

Remove all trailing whitespace from the dalvik team-maintained parts of libcore.
Gentlemen, you may now set your editors to "strip trailing whitespace"...

Removing APIs from dalvik.system that shouldn't have been published.
These APIs were deprecated in Eclair and should disappear in Gingerbread.
See bug 2553600.

Deprecate many of the accidentally-published APIs in dalvik.system.
See bug 2021674 for discussion. I searched Google Code Search to
sample which of these APIs are being used. None of these APIs
were used by applications, so I'm quite confident that removing
them will not break applications or upset developers.
These APIs were neither formerly documented, nor intended for use
by application developers. I am deprecating them now to discourage
their use going forward. We should remove them in a future release.

Fixing Executors to use raw types, which is what RI v5 does.
Also fixing VMStack to hide the new API method.
